  • the fact that the front and rear end portions 51a, 51b intersect with the front and rear waist elastics 23, 33 means that they are indirectly overlapped via the front and rear waist sheets 22, 32 and the back sheet 44 to be intersected.
  • the front and rear end portions 51a, 51b are located inner than the front and rear end edges 41a, 41b of the core 41 in the longitudinal direction Y, that is, they are located on the imaginary lateral center line Q-Q side.

  • the front end edge 40a is located on the skin facing side of the front waist panel 20 and the back sheet 44 is joined to the front waist sheet 22 by known joining means such as a hot melt adhesive (not illustrated).
  • the front end edge 41a of the core 41 is also located in the front waist region 2 such that part of the core 41 is overlapped with the front waist panel 20.
  • a dimension in the longitudinal direction Y of the core 41 overlapping with the front waist panel 20 is about 50 to about 90 mm.
  • an inelastic region 61 in which the front waist elastics 23 are not positioned is formed.
  • the inelastic region 61 may be formed by disposing no front waist elastics 23.
  • a first elastic region 62 is formed in such a manner that the elasticity of the front waist elastics 23 is exerted thereon.
  • the first elastic region 62 is to partially overlap with the core 41. That is, part of the front waist elastics 23 is attached so as to overlap with the lateral edges 41c of the core 41, in which a dimension of the overlapping region in the lateral direction X is about 15 to about 35 mm. Accordingly, the contractile force of the front waist elastics 23 is exerted at the lateral edges 41c of the core 41.
  • a second elastic region 63 is formed in such a manner that the elasticity of the front waist elastics 23 is exerted thereon.
  • the second elastic region 63 is formed by the front waist elastics 23 being continuous between the lateral edges 20c of the front waist panel 20.
  • the contractile force of the front waist elastics 23 is not exerted on the core 41, hence the core 41 does not shrink in the lateral direction X. Since no gathers are formed on the core 41, the area to contact with the wearer's skin is not decreased.
  • the rear end edge 40b of the crotch panel 40 is located on the skin facing side of the rear waist panel 30 and the back sheet 44 is joined to the rear waist sheet 32 by known joining means such as a hot melt adhesive (not illustrated).
  • the rear end edge 41b of the core 41 is located in the rear waist region 3 such that part of the core 41 is overlapped with the rear waist panel 30.
  • a dimension of the core 41 in the longitudinal direction Y overlapping with the rear waist panel 30 is about 20 to about 50 mm, which is smaller than that of the front waist panel 20.
  • an inelastic region 64 in which the rear waist elastics 33 are not positioned is formed.
  • a first elastic region 65 is formed in such a manner that the elasticity of the rear waist elastics 33 is exerted thereon.
  • the first elastic region 65 is configured to partially overlap with the core 41. That is, part of the rear waist elastics 33 is attached so as to overlap with the lateral edges 41c of the core 41. More specifically, a dimension of the region in which they are overlapped in the lateral direction X is about 5 to about 20 mm. Accordingly, the contractile force of the rear waist elastics 33 is exerted at the lateral edges 41c of the core 41.
  • the region in which the rear waist elastics 33 are overlapped with the lateral edges 41c of the core 41 in the rear waist region 3 is to be smaller than that of the front waist region 2.
  • the core 41 does not shrink in the lateral direction X, thereby the area capable of facing the skin is never decreased. Accordingly, it is possible to prevent the absorbing capacity from decreasing caused by a decrease in the area facing the skin.
  • the first elastic region 65 is in close contact with the wearer's skin by the contractile force
  • the inelastic region 64 is not in close contact with the skin, in which it bends with the lateral edges 41c as a base point so as to be spaced away from the wearer's skin.
  • the stiffness thereof becomes larger in the vicinity of the lateral edges 41c than in other regions such that it more easily bends in the center of the core 41 having low stiffness in a direction spaced away from the skin.
  • the core 41 is pushed toward the wearer's skin by the contractile force of the elastics, hence it is not spaced away from the wearer's skin.
  • a second elastic region 66 is formed so as to exert the elasticity of the rear waist elastics 33.
  • the second elastic region 66 is defined by the rear waist elastics 33 continuous between the lateral edges 30c of the rear waist panel 30.
  • a dimension between one of a plurality of rear waist elastics 33 located closest to the crotch region 4 side in the second elastic region 66 and the rear end edge 41b of the core 41 in the longitudinal direction Y is to be about 5 to about 20 mm, preferably about 7 to about 15 mm.
  • the gasket elastics 51 extending in the longitudinal direction Y are overlapped at least with part of the rear waist elastics 33, the crotch panel 40 is contracted in the longitudinal direction Y, and thereby a step may more easily be generated in the rear waist panel 30.
  • the core 41 bends to a direction to be spaced away from the wearer's skin in the lateral direction X, and a step is formed by the rear waist panel 30 at the rear end edge 41b.
  • the core 41 and rear waist panel 30 form a pocket 70 to retain excretions such as feces or the like.
  • the excretions are temporarily retained in the pocket 70, and thereafter fluid may be absorbed by the core 41.
  • the core 41 is spaced away from the wearer's skin so that it is possible to prevent the core 41 from staying in close contact with the wearer's skin via the body side liner 42 causing dampness or diaper rashes.
  • the second elastic regions 63, 66 of the front and rear waist panels 20, 30 are spaced apart from each other outboard of the covering sheet 49 in the longitudinal direction Y. More specifically, the front and rear waist elastics 23, 33 attached in the second elastic regions 63, 66 do not overlap with the front and rear end edges 49a, 49b of the covering sheet 49. The front and rear end edges 49a, 49b are located inner side than the front and rear waist elastics 23, 33 in the longitudinal direction Y.
  • a nonwoven fabric or the like in which fibers are mechanically entangled is used as the covering sheet 49, it may be a sheet having a relatively large bending stiffness and the sheet may be difficult to contract even by the contractile force of the elastics.
  • the front and rear waist elastics 23, 33 are not overlapped with the covering sheet 49, it is possible to ensure that the front and rear waist panels 20, 30 contract and to keep them in close contact with the wearer's body. Furthermore, in the rear waist panel 30, the second elastic region 66 is ensured to contract, hence the pocket 70 may be easily formed.
  • the front and rear waist panels 20, 30 include a two-folded sheet which is formed by folding back a piece of sheet. At the front and rear end edges 40a, 40b of the crotch panel 40, only the body side liner 42, the leakage-barrier sheet 43, and the back sheet 44 are overlapped. Therefore, in the region in which these front and rear waist panels 20, 30 and the front and rear end edges 40a, 40b of the crotch panel 40 are overlapped, a relatively small number of sheets, five in total, are overlapped. Since the number of overlapping sheets is small, the stiffness in this part is also relatively small, the front and rear waist panels 20, 30 are ensured to contract by the contractile force of the front and rear waist elastics 23, 33.
  • the front and rear waist elastics 23, 33 are not located in the inelastic regions 61, 64. However, if the elasticity thereof is smaller than that of the first elastic regions 62, 65 so as not to contract the core 41, elastics may be attached.
  • the core 41 bends easily in the lateral direction X.
  • the mass per unit area of the core 41 in the central portion in the lateral direction X may be differentiated from that on the lateral portions so that a difference in stiffness is obtained.
  • the core 41 may include region(s) in which no or scarce core material is present.
  • the core 41 may be subjected to a press work either in the central portion or on lateral portions so as to obtain a difference in stiffness.
  • a slit extending in the longitudinal direction Y or lateral direction X may be formed in the core 41 so as to partially lower the stiffness thereof.
  • the crotch panel 40 is attached with the distal elastics 52, which causes the second cuff 48 to contract in the longitudinal direction Y. Together with this, the entirety of the crotch panel 40 is contracted in the longitudinal direction Y. The vicinity of the rear end edge 41b of the core 41 is also contracted in the longitudinal direction Y, thereby forming the pocket 70 more easily.
  • the pocket 70 is formed in the rear waist region 3, however, it may be formed in the front waist region 2 or front and rear waist regions 2, 3.
  • an inelastic region is formed in a region overlapping with the core; a first elastic region is formed on lateral portions thereof; a second elastic region is formed outboard thereof in the longitudinal direction; and a distance between the second elastic region and the second core-end edge is 5 to 20 mm.
  • the diaper 1 may be formed in such a manner that the front waist region 2, rear waist region 3 and crotch region 4 are continuously formed.
  • first and second are used to merely distinguish the components, locations or the like having similar names.
  • first waist region means one of the front and rear waist regions, and “second waist region” means the other.
